An objective of the present invention is to provide a powder dispersion composition capable of achieving a high ultra-violet protection effect and reducing the burden on the skin while maintaining the feeling of freshness and good elongation required for oil-in-water emulsion cosmetics.The powder dispersion composition is a powder dispersion composition in which powder is dispersed, wherein the average particle size of the powder in the dispersion composition is 10 times or less of the primary particle size of the powder, the polydispersity index (PDI value) of the average particle size in the dispersion composition is 0.14 or less, and the absorbance per 1% of the powder is 150 or more.本發明所欲解決之課題在於，提供一種粉末分散組成物，該粉末分散組成物可保持水中油型乳化化妝料所要求之水潤感以及展開性優良的使用感，同時可減輕對肌膚造成的負擔感，且能夠達成高防禦紫外線之效果。本發明所提供之粉末分散組成物係粉末經分散的粉末分散組成物，其中，前述分散組成物中的粉末的平均粒徑為粉末之一次粒徑的10倍以下，前述分散組成物中的平均粒徑的多分散性指數(PDI值)為0.14以下，前述粉末每1%的吸光度為150以上。
